I'd turn off IP / TCP / UDP checksum offloading on your NIC if it supports it, and see if you are getting network layer checksum errors. If the IP checksum is wrong, then it happened on the last hops between the NIC and memory or across the previous network hop. ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
Re: arp: unknown hardware address
The Address Resolution Protocol (ARP) contains an address format identifiers as part of the frame format. This is so it could be used as generalized solution to discover different types of addresses on a broadcast network. For IP, the address format in the frame ought to be (as I recall) 0x0800 to denote an IPv4 protocol addresses and 0x0001 to denote Ethernet hardware addresses. It seems like some other host on your network has likely emitted malformed ARP messages.

I'd also suggest looking at Lua, as someone else mentioned. It's BSD licensed, and written explicitly for small footprint, embedded applications. There's a port to the Lego Mindstorms controller, for example. The Lua language is written in ANSI C, and has a small set of well defined interfaces to the OS for opening files, memory allocation, etc. There are a number of web based Lua application environments; google for "Lua Kepler" for one such example. There's also a couple of Wiki platforms written in Lua. I think of Lua as the sort of tool you might use these days as compared to Tcl some years ago.

There's a UI change in the zfs command, and to see snapshots, you have to explicitly ask for them: It's a known change made to the zfs tool somewhere around v11 or so. It's documented in all the Solaris notes about ZFS. You have to explicitily list the type of dataset(s) you want to list with "zfs list". By default, it only shows filesystems. You even have to use -t if you want to list volumes. Reading up on the Solaris docs for ZFS is quite enlightening. :) We might want to update the zfs(1) man page in the examples for the 'list' subcommand.

Re: ZFS NAS configuration question
I built a system recently with 5 drives and ZFS. I'm not booting off
a ZFS root, though it does mount a ZFS file system once the system has
booted from a UFS file system. Rather than dedicate drives, I simply
partitioned each of the drives into a 1G partition, and another
spanning the remainder of the disk. (In my case, all the drives are
the same size). I boot off a gmirror of two partitions off the first
two drives, and then use the other 3 1G partitions on the remaining 3
drives as swap partitions. I take the larger partitions on each of
the 5 drives and organize them into a raidz2 ZFS pool.
My needs are more relating to integrity of the data vs. surviving a
disk failure without crashing. So, I don't bother to mirror swap
partitions to keep running in the event of a drive failure. But
that's a decision for you to make.
It's not too tricky to do the install; I certainly didn't need to burn
a custom CD or anything. There are some fine cookbooks on the net
that talk about techniques. For me, the tricky bit was setting up the
geom gmirror, which you could probably do from the fixit CD or
something. I just did a normal install on the first drive to get a
full FreeBSD running, and then "built" the mirrors on a couple of
other drives, did an install on the mirror ("make installworld
DESTDIR=/mnt") and then just moved the drives around. And I did a
full installation in the 1G UFS gmirror file system, just to have an
full environment to debug from, if necessary, rather than just a /boot.
Just some ideas..

Hey
I am not entirely sure if this question belongs here or to another
list, so feel free to direct me elsewhere :)
Anyways, I am trying to figure out the best way to configure a NAS
system I will soon get my hands on, it's a Tranquil BBS2 (
http://www.tranquilpc-shop.co.uk/acatalog/BAREBONE_SERVERS.html ).
which has 5 SATA ports. Due to budget constraints, I have to start
small, either a single 1,5 TB drive or at most, a small 500 GB system
drive + a 1,5 TB drive to get started with ZFS. What I am looking for
is a configuration setup that would offer maximum possible storage,
while having at least _some_ redundancy and having the possibility to
grow the storage pool without having to reload the entire setup.
Using ZFS root right now seems to involve a fair bit of trickery (you
need to make an .ISO snapshot of -STABLE, burn it, boot from it,
install from within a fixit environment, boot into your ZFS root and
then make and install world again to fix the permissions). To top that
off, even when/if you do it right, not your entire disk goes to ZFS
anyway, because you still do need a swap and a /boot to be non-ZFS, so
you will have to install ZFS onto a slice and not the entire disk and
even SUN discourages to do that. Additionally, there seems to be at
least one reported case of a system failing to boot after having done
installworld on a ZFS root: the installworld process removes the old
libc, tries to install a new one and due to failing to apply some
flags to it which ZFS doesn't support, leave it uninstall, leaving the
system in an unusable state. This can be worked around, but gotchas
like this and the amount of work involved in getting the whole thing
running make me really lean towards having a smaller traditional UFS2
system disk for FreeBSD itself.
So, this leaves me with 1 SATA port used for a FreeBSD disk and 4 SATA
ports available for tinketing with ZFS. What would make the most sense
if I am starting with 1 disk for ZFS and eventually plan on having 4
and want to maximise storage, yet have SOME redundancy in case of a
disk failure? Am I stuck with 2 x 2 disk mirrors or is there some 3+1
configuration possible?
Sincerely,
- Dan Naumov

Re: ZFS NAS configuration question
The system that I built had 5 x 72GB SCA SCSI drives. Just to keep my own sanity, I decided that I'd configure the fdisk partitioning identically across all of the drives. So that they all have a 1GB slice and and a 71GB slice. The drives all have identical capacity, so the second 71GB slice ends up the same on all of the drives. I actually end up using glabel to create a named unit of storage, so that I don't have to worry about getting the drives inserted into the right holes.. I figured that 1GB wasn't too far off for both swap partitions (3 of 'em) plus a pair mirrored to boot from. I haven't really addressed directly swapping another drive of a slightly different size, though I've spares and I could always put a larger drive in and create a slice at the right size. It looks like this, with all of the slices explicitly named with glabel: r...@droid[41] # glabel status Name Status Components label/boot0 N/A da0s1 label/zpool0 N/A da0s2 label/boot1 N/A da1s1 label/zpool1 N/A da1s2 label/swap2 N/A da2s1 label/zpool2 N/A da2s2 label/swap3 N/A da3s1 label/zpool3 N/A da3s2 label/swap4 N/A da4s1 label/zpool4 N/A da4s2 And the ZFS pool references the labeled slices: r...@droid[42] # zpool status pool: z state: ONLINE scrub: none requested config: NAME STATE READ WRITE CKSUM z ONLINE 0 0 0 raidz2 ONLINE 0 0 0 label/zpool0 ONLINE 0 0 0 label/zpool1 ONLINE 0 0 0 label/zpool2 ONLINE 0 0 0 label/zpool3 ONLINE 0 0 0 label/zpool4 ONLINE 0 0 0 errors: No known data errors And swap on the other ones: r...@droid[43] # swapinfo Device 1024-blocks UsedAvail Capacity /dev/label/swap4 10441920 1044192 0% /dev/label/swap3 10441920 1044192 0% /dev/label/swap2 10441920 1044192 0% Total 31325760 3132576 0% This is the mirrored partition that the system actually boots from.

Matthew X. Economou wrote: not very important but wouldn't it be better to set the checksum to 0 instead of some arbitrary (?) and confusing value then ? No, as not setting the checksum is a (minor) optimization. Setting that field to any arbitrary constant means at least one completely unnecessary CPU instruction per datagram. Best wishes, Matthew However, since it is a 1's complement checksum, there is a distinguished value (all zero bits) that you could set the checksum field to that wouldn't occur for a normal computed checksum. Since the presence of a checksum is mandatory for TCP, you can use this trick and external software could "know" that it's a distinguished value. This is similar to UDP, where the protocol allows the "no checksum present" case by setting the checksum field to all zero bits. I suspect the overhead isn't the CPU instruction, but the memory reference. If you manipulate the checksum field to the distinguished value at the time the other fields are written, they they'll all get written out to memory when the cache line is flushed. You've already got to initialize the Urgent Pointer field, which is the other 16 bits in the same 32 bit word. If you were really clever, you could make a union to cover both fields and zero both out in the same store instruction. louie ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
